Y i 70 NZZ 1li/ioni iwiay conce/ol:

Be 1t known that I, Geenen F. MoCAiinY,

a citizen ot "tlu' Vnited States. and residentr of the city of rovidence, in the county of Providence and I@tate of Rli'ode island, have invented certain new and useful improvements in liraiding-Machincs. of which the following is :i specification.,

This invention relates to improvements in braiding machines more particularly to the so-called rotary type of braider in which the yarn supplies a're .arranged in series to revolve in opposite di -ections: about a eonin mon axis.

The invention ha's for its object to provide means whereby the yarn supplies of one set may be carried by the shuttles and supported thereby from their 4upper ends for the purpose of increasing the eiiiciency and renderingr more eilective the operation ot the machine.

A further object of the invention is to position the yarn-tension weight standards of both sets. of supplies on a corresponding incline to the common axis about which they revolve and rotate these carriers in opposite directions and in different planes, whereby the yarn tension devices of both sets may be so positioned that under action of centrifugal force an equal tension will be exerted on.

both sets of supplies. which is essential in the production of a uniform product.

The nature and advantages of the invention will be better understood when the tol lowing detail description is taken in con nection with the accompanying drawings, the invention residing in the combination 'and arrangement of parts as claimed.

In the drawings forming part ot this speeitieation, like numerals of reference indieate similar parts in the several views and Whereinz- Figure 1 is a side elevation of the machine partly in section.

lVith reference to the drawings. 20 designates the base-plate of the machine. which is supported on usual legs 2l. 0n this base plate are upright frame rods Q2 which Support' the outer ring or member of the. raceway plate 23 and also support the upper frame members 24. Ou this base-plate 20 I hav(` vfixed a tubular standard Q5 to which is secured the inner section 2G of the raceway. which section is provided with alternate spaced-apart'shuttle guiding surfaces 27 which, as shown in Fig. 2, are formed on the are of a circle and cooperate with the alternate shuttle guiding surfaces 28 of the outer racewayinember 23 to form a ri ng for the support of the traveling shuttle (pres ently described). A spaee 2t) being provided between the adjacent end` of the inner and outer guiding members. through whieh the yarn 30 is eaused to pas.` as it` leads' from each of the lower supplies Ill through their respective guide eyes 252 to the point of braiding 253 and is earried in a serpentine path alternately over and under the shuttles and the upper series ot' supplies earried thereby as illustrated in l"ig. 4.

(in the plate 34. whieh is mounted to rotate ou the ball bearings 35. aetualed by the driving pulleys '50 through the shalt 5h'. clutch 3H and gears 2li' and M is mounted the lower set ot' supplie` lo be rotated in one direction. llaeh suppliof this set romprises a base 4l whieh is mounted on the revolving plate ill and whieh base is arranged to support a vasion weight guide bar 42 which extends in au upward direetion on au iueliue to the eorninou axis' about whieh this set ot' ysupplies rotates. The upper end of this weight guide is arranged to support a spring pressed lateh 48 for engaging the spool ratehet 44 of the bobbin 2li. into the low'er end ot' whu'h spool projeets a short spur 4G which extends into the hole through the sp'ool to retain its lower end in position. rlhe usual weight JJ being pretura ily employed to slide on the weight guide to apply the required tension to the Yam i The shuttle member 48 has a ventral web '49 eonneeted to the upper and lower pairs of flanges 5U and 5l all of wbieh are formed on the are of a eirele neeessary to engage and slide ou the raeewav yseetions as the shuttle is driven in a circle..

lelow this raeewayeiwaging portion of the shuttle. l have formed a thread-guiding plate 52 which is pointed at the front end at 53 and preferably rounded at its rear end 54. for the purpose oi engaging and guiding the yarn either over or under the shuttle.`

0n the under side ot' this guide-plate lm ve secured a tubular varn guiding and proteeting member 55 to the outside. of which. is secured the weight guide 5G, a weight 57 being'mouuted to slide thereon. A yarn guide-hole 58 is provided to permit the yarn 59 to pass'out` down around the weight 5T and up through the tubular opening 60 in the shuttle. head. i

Vithin this tube -l have mounted a bobbin (ilhaving a ratehetspool head (i2 at its upper end engaged by a spring-pressed latch 63, the end 64 of which latrh extends out` through the opening in the side wall `ol" the tube into position to be engaged by an upward throw of the weight 57 to release the spool when more yarn is required. This spool is held in position on the central rod (i5 by a lateh liti which iS pivoted in the end thereof.

The raeeway guides 2T and 28 are set on an angle so as to reeeive the lshuttles 48 and permit them to Isupport the upper set of yarn supplies below the` raeeway and on an ineline. the angle ol' whieh inelination is sub weights are pmitioned at different distances from the eeuter around which they rotate.

ln order to drive this upper set of yarn supplies in' a direetion opposite to that of the rotation of the lower set of yarn snpplies` l have provided a tubular shaft 67 whieh is' rotated from the gear 39 through the gear (3S to the upper end of which tubular yshaft l have connected the drive-dog plate ($9. This guide plate is best illustrated in Figs. 7 and 8 as being provided on its under side with a multiplicity of radial Slots 7U in whiehthe drive dogs 7l. are guided, the ends T2 of these dogs being adapted to engage the recesses T3 in the shuttle flange and these dogs are yoked together in pairs by the plate 7l. which plate is pivoted at 75 to the under side of the dog guide plate G9. One of each pair of these drive dogs is provided with a guide roll T6 which extends down into the eam groove 77 in the cam plate 78 whereby. as best illustrated in Fig. 4, each pair ol' drive dogs is reeiproeated in and out at the proper time and at the points 79 in this ram, lo permit the yarn from the lower supply to pass the shuttle of the upper supply Vwithout at any time entirely disengaging the drive from the shuttle, that is, before one dog is entirely withdrawn from the shuttle the other of the pair engages the,

f the upper Supply members.

ln order to provide simple and elective means for lifting this yarlfout of itsnornial aostion, I have mounted a fixed cam meinr 80 on the upper end of the fixed rod 81.,

which cam member is provided with recesses 82 and raised portions 83. As the lower supplies rotate they cause the yarn 3() to ride from the lower portion 82 of this cani plate up onto the raised portion 83 thereot'. as illustrated in Fig. 6, thereby lit'ting the `varn to a position above the point 53 of the guide plate whereby this plate then upon cngaging this varn rides under it and guides it over the upper supply and so, as illustrated Ain Fig. 4, the shuttles are caused to ridc alternately under and over this yarn 3G as the two sets of supplies are revolved "in opposite directions.

As the yarn is braided at the point 84 it is lead over the take-up wheel 85 and conducted away, which wheel is shown as being driven from the main shaft 3T through gears 86, upright shaft 87. worm 88, spur gears 89, miter gears 9() and worm wheel .)l which is mounted on the take-up wheel shaft 92.

In order to stop he machine when the yarn breaks or for any reason becomes too slack, in either of the sets of supplies, I have provided a stop motion which consists ot a clutch 93 on the shaft 37, which clutch is -adapted to be withdrawn from its opposite clutch member 3H by means of the arnrtlfi through the connector lever U6. and upright rod DT on whlch rod is located a doo- Sie: to he engaged by the tension weighty 5r of the upper set. and a dog 99 to be engaged b v the tension weight 47 of the lower set when either ot' these weights is, for any reason, moved to its low or stop position. rlbe handle lill) is also provided hy which thisV stop motion may be manuallyy operated when desired.

liv my improved construction of rotar)v braider it will be noted that l support the upper set ol' supplies b v their nppcr ends and below the racewalv and b v mounting both sets on the corresponding incline to rotate in ditl'crent planes l am enabled to position the tcnsion weights ot' both sets so that they are disposed to revolve at substantiallxv the same distance `from tbc connnon center aboutl which tbev rotate. whereby centrifugal torce acts upon tbc \\'cights ot' both sets equalliy to produce a nnii'orin tcn sion on the vai-n trom the supplics troni the dill'ercnt sets. iv inv iinprovcd construction l ain enabled to reduce the nlnnbcr of parts and have provided a machine which may.' be run at very high rate oi` speed to iir crease the production which is of a uniform quality. A

By the term shuttle l include thc whole member or element which travels in the raccwa v arid supports the snpplr of yarn or thread.
